1. The problem statement, all variables and given/known data A mass of 0.3kg is suspended from a spring of stiffness 200Nm-1. If the mass is displaced by 10mm from its equalibrium position and released, for the resulting vibration calculate: The maximum velocity of the mass during the vibration. 2. Relevant equations v = Aωcos(wt+∅) 3. The attempt at a solution Now ω = 25.82cos. so v = A 25.82cos (25.82t+∅) So now i have to find A (amplitude) and t (displacement) Is displacement the same as the amplitude? Not sure on how to find the amplitude? Any guidance would be appreciated.
